@BillLotz I don't profess to be a D2M expert as I use other software for photogrammetry, but the terminology is largely the same across platforms:
1. have you enabled ghost filtering in the orthomosaic creation?
2. does D2M support RGB point cloud classificaiton? If so, can you classify ground points, build a DTM from just the ground points, then re-run the orthomosaic creation using the DTM as your surface? This would resolve any strange artifacts in vertical components of the ortho, becuase it wont be trying to interpolate down the sides of vertical structures.
3. enable rolling shutter correction as @TrentReeder suggests.
4. can you edit the seamlines in D2M like with other software and redraw around objects with poor image quality to replace the image being used?
